Upgrade issue with Elastic Stack 5.6.0, workaround option until fix is available

Elastic Stack Kibana
6

I upgraded to 5.6.0 and hit this issue, but successfully applied the hotfix, 8132-patch.sh. At this point Kibana was happy and working as expected.

I then upgraded ES and Kibana to 5.6.1. Now Kibana is back in a "Red" state with some different errors. ES cluster status is "Green". Is this related to the hotfix patch? Or something completely new?

I also see this show up in Kibana's stdout log over and over.

{"type":"log","@timestamp":"2017-09-20T10:57:28Z","tags":["info","elasticsearch"],"pid":17028,"typeName":"url","typeMapping":{"properties":{"accessCount":{"type":"long"},"accessDate":{"type":"date"},"createDate":{"type":"date"},"url":{"type":"text","fields":{"keyword":{"type":"keyword","ignore_above":2048}}}}},"message":"Adding mappings to kibana index for SavedObject type \"url\""}

No timestamps in the stderr log, but here's a snippet from that:
